Customers are asking, can we....

Leverage existing assets?

Leverage modern architectures?

Leverage existing skills and attract new skills?

Leverage a common development environment for all development teams?

Leverage my development spending better?

??

Your current application programming environment is a key inhibotor

Why EGL? Today’s key development challenges

Costly to maintain

Monolithic

Hard to repurpose

Skills silos

Skills mismatch

Skills erosion

Proliferation

Coexistence

Complexity

Existing Applications Skills Platforms / Middleware

Why EGL? Because building applications today is not easy

Learn and master myriads of

programming languages and semantics

middleware interfaces

programming paradigms and styles

frameworks and libraries

Constantly emerging new technologies

EGL and Rational Business DeveloperA simple, robust, unified approach to end-to-end construction of application and services that shields developers from intricacies of runtimes and middleware

The power of the LanguageSimple and familiar…. yet robust and complete

Rich data types Primitive

Simple (int, string, boolean, etc.) Complex (any, arrays, dynamic arrays, dictionaries, array dictionaries, etc.)

User defined Data Parts

Keywords Case, if-then-else, while, for loop, for loop cycling through a database

result set, etc.

High power language capabilities Automated Casting (e.g. using AS operator)

Mixing data types in assignments and expressions

Exception handling

Rich libraries of built-in functions Math, string, date/time, system, i5/OS objects APIs

Robust integration with existing investment or access to low level APIs Call RPG, COBOL, C, etc.

Full Java interoperability Invoke Java from EGL (map Java classes with EGL External Types) Invoke EGL from Java

Language

8


The power of Abstractions and Declarative programming Data access:

“Records” provide access to: SQL, Indexed, Relative, Serial, DL/I, Service data, Message Queues

Common Verbs for data access (Get, Add, Replace, Delete). Allows complete access to SQL statement if needed. Common Error Handling.

Remote Invocation Call COBOL, RPG, C, Java. Linkage information separated from code. Data mapping, protocol invocation all resolved at runtime, NO code necessary

User Interface: EGL “handlers” hide complexities of

Web (JSF) UI Reports (BIRT) Portlets Rich Web (Ajax)

Validation/Editing Rules: Via properties in “Data Items. Define formatting & validation rules in a common place. Reuse data items for Records, screens, web pages, reports.

Abstraction

Declarative

9


The power of tools

Web development Integrate seamlessly with Page Designer and JSF tools

EGL native coding within JSF, mask all JSF complexity

Drag drop, code behind

Powerful IDE Smart EGL editor, Code templates and snippets, Code completion

SQL visualization, editing, validation

References and declarations, Refactoring

Model Driven Development tools Generate fully functional CRUD applications from UML models or Database schemas

including default JSF, and EGL or Web Services!

Tools

Integrated interactive Debugger State-of-the-art

No compile necessary, just click and aniimate execution as you define the code!

Full control, step, run, reposition, skip, change variables content, etc

10


The power of ServicesBuilt into the language

Service part: a generatable part containing code that will be accessed:

from EGL code by way of a local or TCP/IP connection (EGL Service). from any code by way of an HTTP connection (EGL Web service).

Interface part: Used to access external services as EGL services or simply to provide

separation of concern.

At development time… Focus on the business logic Implement SOA design elements: services and interfaces Leverage existing business developers for new SOA development Ignore deployment targets/technology while coding/testing

Deploy EGL services…To any platform (Java to WAS/Tomcat, COBOL to CICS, i5/OS ) As a Web service (uses SOAP) As a private service (uses CICS ECI or TCP)

Leverage external web services… EGL Interfaces

represent external web servicesare created via import from WSDLallow the EGL developer to stay within the context of EGL programming

Why Rich Internet Applications (RIA)? Applications are responsive and user friendly (user productivity) Applications can leverage services “mush-up (business innovation)

Why is it hard to create RIA Need to know many low level intricate technologies Compound the slill/tool silos and fragmentation Currently domain of “tech heads”

EGL and Rich UI Includes visual composition, libraries of RUI widgets

Instant deploy/visualize while you code

Fully open and extensible

Easily integrate/consume any service (REST or SOAP)

Single language end-to-end

Brings legacy data and assets to Web 2.0

Arkansas Data ServicesDeliver B2C retailer Web solution

Challenge:Deliver a Web based B2B ordering system for wholesale men’s formalwear rental business with little to no web development experience

Solution:Leverage existing Order entry system (RPG) core functionality with a completely new JSF based interface

Results:In the time allocated for a prototype, ADS had the entire system up and running ready for final test

“Our original estimate for this project using Java/JSF was 4-6 months and our client would never accept that. With EGL we were ready for test in 4 weeks! ”

Rusty Gadberry - Arkansas Data Services

KBCUnify application dev across platforms and transaction managers

Challenge:

High costs and low responsiveness to business: redundancy and duplication across IT groups, fragmentation of languages and tools

Solution:

Leverage EGL to achieve the Cross-System components development, eliminate skills silos among their dispersed development teams, eliminate various platform specific languages and tools

Results:

Enable component based architecture. Shift to component based architecture, product factories and multi channel.

Created interchangeable developers. Shift from monolithic (3270) applications to browser based and open systems. Transform 600 mainframe developers to multi platform developers (Unix, mainframe, WAS, IMS).

“… We want to avoid the ‘skill silos,’ what we really need is a large group of general developers who should not worry about target platforms and focus on developing business components, and only a small number of technology specialists, so that we can swiftly allocate general developers to upcoming business needs… EGL is helping us achieve this goal…”

- Lieven Gouwy, IT Architect, KBC, Redmonk Podcast
